How are we defining "being in love"? Is it just your feelings for someone or must it require that person also having the same feelings for you? If it is the latter, then zero.
You can't tell what someone else's feelings for you are.
I've had 3 long term, live-in relationships, in which I was definitely in love, and it was returned, as far as I can tell. I've had at least three purely emotional (nothing physical) relationships where again I was in love, and the claim was that it was returned. I've also fallen in love a couple other times, where it was probably not returned - I volunteered my feelings, and no reply was forthcoming.
Since love is forever, I try not to fall too many times.
